This invention relates to a pressure lubricating system particularly adaptable for vehicles, and the lubrication of the various chassis connections therein under pressure.

The invention further resides in the mounting of a grease gun on the vehicle which is permanently connected with the various parts of the chassis to be lubricated.

The principal obj ect of the invention is to provide a grease gun adapted to selectively force grease or other lubricating substance through suitable connections to the parts to V be greased, while permitting the convenient manipulation and control thereof so as to 5 simultaneously actuate the gun and open the check valve to the part to be lubricated.

The full nature of the invention will be more fully understood from the accompanying drawings and the following description go and claims.

Fig. 1v is a side elevation of the selective control valve mounted upon the vehicle dash boardr Fig. 2 is a section taken through a portion of the instrument board showing the connected with the gear and crosshead frame.

The lubricant contained in the receptacle 114 40 then drops by gravity into the cylinder 113 and is forced therefrom by the reciprocable action of the piston through the tube 129 into the valve housing 140 which is mounted on the rear of the dash board 131.

indicating disk 132 provided with apertures 133 for receiving a projection on the handle 134. Said handle is secured to the shaft 135 extending rearwardly through the dash and connected with the annular valve disk 136 control switch and selective valve mechanism is secured to the dash board and the motor On the front of the dash board there is an.

whereby saidvalvewill berotated by the rotation of the handle 134'. Said disk is provided with a singlefpassage-way 137 which registers with an annular groove 138'formed in the block 139 and communicating with the intake tube129. Surrounding the rotatable selective valve disk 136-there' is a housing 140 into which the various individual tubes141 are connected, which lead to various parts of the vehicle. Thus, when the handleis positioned to engage a certain notch 133','thepassage 137 will be caused to register with the distributing tubei 141 opposite that notch leading-f to a predetermined pm; of the chassis. r

" For controlling ft-hemotor, the indicating disk 132 is provided with an annular contactw ing ring142 with whi'chithe handle engages when extending through oneof the apertures 133. The contacting ringf 142$is electrically connectedwith one terminal of the motor by "a cable extending through an aperture' in the dash boardv 110. 'Tlie otheriterminal of the motoris connected by a suitable cable'directly with the shaft 135'from which'electric contactmay bemade with therring 142 through the medium of the handle134,.wher'eby the circuit through the motor'may be completed for driving the same when the handle. 134 moved to a positionso that the knob or projection on the end thereofiwill extend through one of the apertures 133 so as to contact with the ring 142. It will'be inotedthat when said projection is brought to a position to extend through one of the apertures thevalve disk is brought-in position'for opening the passage fromthe receptacle 114 to the correspending selected lubricant delivery tube 141.

By means of this arrangement, by one operation or adjustment of the handle134 a given part of the lubricant-maybe selected for lubrication whilei the power is simultaneously applied. 5

When the device is applied to the motor vehicle as a permanentinstallation and it is desired to lubricate a given part of the vehicle, the handle 134. is rotated'so that the projection thereon extends through oneof the'apertures andrc'ontacts with the ring 142, thus energizing the motor and causing the lubricant to be pumped through the selected conduit leading thereto, said conduit communieating with the receptacle by reason of the selective positioning of the handle.

5 The invention claimed is:

1. The combination with a vehicle, of a power lubricator mounted thereon, said lubricator including a lubricant containing receptacle, a plurality of tubes connecting said receptacle with'the individual parts of the vehicle to be lubricated, a valve mounted between said receptacle and tubes, power driven means for forcing lubricant from said chamber through said valve under pressure when said valve is in open position, and a handle for selectively positioning said valve for permitting the lubricant to be forced therethroughinto one of said tubes while preventing lubricant from passing through the other tubes, and means controlled by the position ofsaid valve for actuating said power driven means when said valve is in open position with respect to said selected tube. v

2. The combination with a vehicle, of a power lubricator mounted thereon, means as sociated therewith for selectively lubricating individual parts of said vehicle, an electricmotor, actuating mechanism driven by said motor for forcing the lubricant under pressure to such selected part to be lubricated, and

a single control for effecting a channel of communication betweensaid lubricator and said selected part to be lubricated and simultaneously energizing said motor.

85 3. The combination witha vehicle, of a power lubricator mounted thereon, including a lubricant containing chamber, a plurality of channels of communication. with difi'erent parts of said vehicle to be lubricated, a com- 40 mon channel of communication therewith connected with said chamber, a control for selectively placing one of said first mentioned channels of communication in connection with said main channel'of communication,

a manipulating handle for actuating said control and indicating the selected channel of communication, an electric motor for forcing the lubricant through said channels of communication, and means associated with said handle for energizing said motor upon the selective positioning thereof.

.4. The combination with a vehicle, of a lubricator mounted thereon, means associated therewith for selectively lubricating individual parts of said vehicle, actuating mechanism for forcin the lubricant under pressure to such selected part to be lubricated, and a single control for effecting a channel of communication between said lubricator and said selected part to be lubricated and simultaneously actuating said mechanism.

In witness whereof, I have hereunto affixed my signature. OHN B. MCFERRAN, JR.
